GF-6060: Initial Cordova notification standards. Will be expanded as alert/confirm/prompt APIs are expanded. Backward compatibility not yet achieved, but planned.
Enyo-DCO-1.1-Signed-off-by: Jason Robitaille <jason.robitaille@lge.com>
Reworked for future window alert/confirm/prompt functions, with fallback for webOS 1-3.x for alert, and console error messages saying confirm and prompt aren't supported on old devices.
